Radiation therapy has greatly revolutionized in the last decades. Its rapid advances are more precise and target localized treatments for various cancers and neuropsychopathies. Techniques like Gamma Knife and CyberKnife allow for highly focused delivery of radiation to minimize side effects. IGRT (Image-Guided Radiation Therapy) would involve real-time monitoring and correction of the treatment plan to ensure optimal accuracy.

Key differences

Gamma Knife

• Technology: It uses a single, focused beam of high-energy gamma rays.
• Procedure: The patient's head is immobilized in a frame, and the radiation beams are precisely aimed at the tumor.
• Treatment Time: Few hours.
• Advantages: High accuracy, minimal invasiveness, and short treatment time.
• Disadvantages: Requires a fixed frame and may not be suitable for large or complex tumors.

CyberKnife

• Technology: It uses a robotic arm that delivers radiation beams from multiple angles.
• Procedure: The patient is positioned on a table, and the robotic arm moves to target the tumor from different directions.
• Treatment Time: Can take several sessions over a few weeks.
• Advantages: Highly flexible, allowing for treatment of complex tumors and moving targets.
• Disadvantages: Longer treatment time and potential for higher radiation exposure to surrounding tissues.

Cost Variation

CyberKnife -The cost of CyberKnife treatment in India can range from INR 5,00,000 to INR 15,00,000 or more.

Gamma Knife - The cost of Gamma Knife treatment in India can range from around INR 75,000 to INR 6,00,000.
